  • Advantages/disadvantages of Glassfish v3 Prelude vs Springsource dm server for Web applications?

    - by cletus
    Both of these appservers are at least in part OSGI based. One (Glassfish) is obviously J2EE while the other isn't. Now I'm at the stage of choosing a platform for a new project and the natural choice is Glassfish v3 Prelude. This does raise the issue of perhaps we should be using S2AP instead. The question then is this: does the springsource dm server offer any compelling reason to use it over Glassfish? And vice versa.

  • Are there any tools for performing static analysis of Scala code?

    - by Roman Kagan
    Are there any tools for performing static analysis of Scala code, similar to FindBugs and PMD for Java or Splint for C/C++? I know that FindBugs works on the bytecode produced by compiling Java, so I'm curious as to how it would work on Scala. Google searches (as of 27 October 2009) reveal very little. Google searches (as of 01 February 2010) reveal this question.

  • volatile vs. mutable in C++

    - by skydoor
    Hi I have a question about the difference between volatile and mutable. I noticed that both of the two means that it could be changed. What else? Are they the same thing? What's the difference? Where are they applicable? Why the two ideas are proposed? How to use them in different way? Thanks a lot.

  • Where is the source archive for my Websphere portal classes?

    - by cringe
    I'm pretty new to Websphere application development and I'm missing the source attachment for all the classes in the com.ibm.wps.* packages in my IBM Rational Application Developer setup. For example the class com.ibm.wps.engine.Command from JAR wp.engine.impl.jar has no source attached. Do I have to install another package with the sources or where can I find it? Also, excuse the question if it is so trivial and stupid... :-}

  • Debugging in Flash CS4

    - by danyal
    Is a watch list hidden away somewhere in the AS3 debugger in Flash CS4? Sorry for asking a simple question like this here - I did spend a while looking around the net first. It's much easier to find the watch list in the AS2 debugger. Thanks, Dan

  • PySVN: is property status "none" equivalent to unchanged?

    - by detly
    I know the practical difference between a PySVN property status of "normal" (has properties, not changed locally) and "none" (has no properties). My question is this: is it ever possible for there to be local modifications to an items properites, and have PySVN report the property status as "none"? I would say no, but maybe there's some corner case I'm missing.

  • Q&A database map like stackoverflow - seperate table for questions titles

    - by Qiao
    I am planning to make Q&A system (quite specific, has nothing to do with IT) I was looking for Stackoverflow database map: http://meta.stackoverflow.com/questions/2677/anatomy-of-a-data-dump/2678#2678 And I am thinking is not it is better practice to make separate table for questions titles. With "firstPostId". Instead of |- PostTypeId | - 1: Question | - 2: Answer So I want to know, why stackoverflow did not use separate table for questions title. Is it "Do not optimize yet" or does it have any logic behind it?

  • why is java.lang.Throwable a class?

    - by mdma
    In java adjectives ending in -able are interfaces Serializable, Comparable etc... So why is Throwable a class? Wouldn't exception handling be easier if Throwable were an interface? Obviously, changing it now is out the question. But could it be made abstract? Wouldn't that avoid the bad practice of throw new Throwable();

  • How to bundle a native library and a JNI library inside a JAR?

    - by Alex B
    The library in question is Tokyo Cabinet. I want is to have the native library, JNI library, and all Java API classes in one JAR file to avoid redistribution headaches. There seems to be an attempt at this at GitHub, but It does not include the actual native library, only JNI library. It doesn't work (for me): when I use this JAR, the JVM does not even seem to find the JNI library which is packaged inside the JAR: java.lang.UnsatisfiedLinkError: no jtokyocabinet in java.library.path (tokyo_cabinet.clj:19)

  • Equivalent of http://www.cplusplus.com/ for C# .net

    - by David Relihan
    Hi Folks I've read through a lot of the "Learn C# .Net" questions just to see if this question was answered already (directly or indirectly). I program mostly in C++ so I find the website http://www.cplusplus.com/ invaluable and there's rarely a day when it is not open in my browser! However, I'm just wondering is there an C# .Net equivalent that people find themselves constantly referencing? The best I'm aware of is: http://stackoverflow.com http://msdn.microsoft.com/en-us/vcsharp/aa336809.aspx http://www.java2s.com/Tutorial/CSharp/CatalogCSharp.htm Thanks,

  • Is there any "modern" text editor with command-line/minibuffer?

    - by Pedro Morte Rolo
    A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or Emacs/CUA are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. It would be nice if there was an editor that would cope with the modern de-facto standards out-off-the-box, but still provide a command-line/minibuffer to perform/explore the commands and learn its shortcuts. Is there such a thing? I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard-shortcut historical baggage. When I reffer to de-facto standards, I am not talking about Windows vs Whatever. Kate, gedit, Eclipse, Intelij or Textmate also follow the norm I am talking about and are not Windows editors. Please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives. Why don't I like emacs and vi: Emacs: Despite CUA mode, emacs has loads of modes that conflict with this (e.g. slime, ruby-mode, etc...) It would be nice to have something that would work out-off-the-box. VI: I do not like that it is Visual/Insert-based. I do not know how to browse the text-editor's commands. I do not like that it is so much tought for the terminal. I believe that it has the same problem that I mentioned for emacs. This question is starting to look like requirement analysis.. As de-facto standards I mean: Ctrol-XCV for cut-copy-paste Ctrol-A for select-all Contrl-Z for Undo Ctrol-Y for Redo Control-F for Searching Contrl-Space for auto-complete Shift-arrow for selection Control-arrow for word-navigation Alt-Arrow for moving

  • Multiple subscribers in NServiceBus

    - by Johan Zell
    Hi. I'm getting started with NServiceBus and have a question about the Pubsub sample. My intention was to have multiple instances of Publisher1 running and receiving the message sent from the publisher. I also hacked the Publisher to only send messages of the eventMessage type. But if I start the publisher and three instances of Subscriber1, only one of them gets the message at a time. why is that? Is it a config setting or something else? /J

  • converting an int to char*

    - by Alexander
    This is a very very basic question and I know one way is to do the following: char buffer[33]; itoa(aq_width, buffer,10); where aq_width is the int, but then I can't guarantee what size of buffer I would need in order to do this... I can always allocate a very large buffer size, but that wouldn't be very nice... any other pretty and simple way to do this?

  • How extensible is Google Moderator?

    - by Masi
    I am trying to integrate vote-up-buttons similar as in Reddit to Google Moderator. However, Google Moderator does not give me Shell access. This suggests me that the only way is to use Vote-up-buttons from an external server set by iframes. I would like to know How can you can assign Iframe_A to a question in Google Moderator? How can you can show an iframe in Google moderator?

  • Getting my head around the practical applications of strong and weak pointers in Objective-C

    - by Chris Wilson
    I've just read the accepted excellent answer to this question that clarifies the conceptual differences between strong and weak pointers in Objective-C, and I'm still trying to understand the practical differences. I come from a C++ background where these concepts don't exist, and I'm having trouble figuring out where I would use one vs the other. Could someone please provide a practical example, using Objective-C code, that illustrates the different uses of strong and weak pointers?

  • Securing Elmah RSS Feeds in ASP.NET website

    - by olivehour
    I followed the answer to this question http://stackoverflow.com/questions/1245364/securing-elmah-in-asp-net-website to restrict access to the elmah handler. However, it seems that adding an RSS feed to Outlook for the URL elmah.axd/rss or elmah.axd/digestrss bypasses the authentication. What's the point of securing the handler if someone can guess the RSS URL and subscribe to a feed of the error log?

  • Book Recommendation for OO design and TDD

    - by whatispunk
    I know there are a ton of books available on the subject but I want one that is recent and describes OOD in terms of TDD, dependency injection, IoC containers, and mocking frameworks. I realize this question is subjective, but I trust in the opinions of SO-ers and am having difficult using Google to provide any real results. Thanks.
